TYPE-XVRITING MACHINE.

10 all who/m.. t muy concern.

Be it known that I, CHARLES H. l-IUN'rn a citizen of the United States, and a resiA dent of Chicago, county of Cook, and lState of Illinois,l have invented certain new and `useful Improvements in 'l`ypc'-\Vriting Ma.-

chines, of which the following is a specification.- i

The invention relates to'iinprovements in typewriting machines and more particularly to visible typewritin'g machines, and seeks to provide a simple and effective key-lever. and type-bar mechanism which will obviate the necessity of employing intermediate sublevers or bell-cranks, such as heretofore usually employed in visible typewriting ma' chines.

A further object of the inventionis to provide an improved arrangement of typebar hangers which afford wide bearings for the type-bars and with which a series of uniform type-bars may be employed.

The invention consists in the features of construction, combinations and 'arrange-l ments Vof parts hereinafter set forth,"illus tratcd in the accompanyintg` drawings and more particularly pointed out in the appended claims.

provided with corner posts 12 and side frames 13. The upper front and rear portions 14 and 15 are sustained from the corner posts 12 and side upright frames 13. The carriage 16 for sustainingl the cylindrical platenl may be of any usual or suitable construction, but as shown, the base of the carriage is -preferably arranged in a plane inclined to an angle of about to the horizontal and is mounted to shift between upper and lower guide rails 18 and 19. i If desired, anti-friction balls or rollers Q0 may be interposed between the carriage and the guide rails thereof,

The type-bars are pivoted upon a segment arranged in frontof and below the platen 17-so' as to strike at a common printing point at the front of and above the centerl of the platen and substantially mid-Way between the front and top of the platen so that the printing point is in the direct line of vision of the operator. With the print- 'ing point so located, the writing is. more easily read than if the printing point is at 'anovided with a. center lug 22 secured by a screw 23 to a cross bar Q4 at. the lower front portion of the machine and the segment is also provided with side lugs 25 secured by screws 26 t0 the side frames 13. The typebars 27 are pivotally mounted in suitable hangers 28 upon the upper face of the typeba-r segment and the type-bars, in idle position, extend upwardly and forwardly from their pivot points at an an le of about 45 to the horizontal to a suitable type-bar rest 29 sustained by the front upper portion 14 of the machine frame.- From idle position, the type-bars swing rearwardly to striking position (shown by dotted lines in Fig. 1) and in which position the type-barsI lare upwardly and rearwardly inclined, as shown, so that the printing point is substantially mid-way between the front and -top, of the platen.

The key-levers 30 are provided as usual at-.their forward free ends -With the rows r 'banks of finger keys 231 arranged at the lower front portion of the machine frame. From the front of the machine the. key-levers extend rearwardly beneath the typebars and their rear fulcrlnned ends are elevated or extend upwardly to a fulcrum 32 at the upper rear portion of the machine frame. Preferably, the forward portions of the key-levers are substantially horizontalwhile the rear portions thereof are inclined upwardly. and rearwardly and are I Vsubstantially'parallel to the type-bar segment 2l. IThe key-levers are all held in normal elevated position with their t'orward ,portions against thc transverse stop-har :53, by springs 34 which are connected at one end to the key-levers adjacent the pivot orA fulcrum 32 and at their other ends to a transverse cross bar 3. By thus elevating the fulc'rum ends of the key-levers to the upper rear portion ot' the machine frame and 'arranging the type-bars upon an upwardly and rearwardly inclined segment in front of and below the platen, the typebars and key-levers may be directly connected by a series of pull-links 3G.

r In the ordinary form of front strike type- Writing machines, the type-bars are horizontal in idle'position or substantially so, and are swung from this horizontal position to a vertical striking position. With a typebar of this" sort it is necessary to exert a horizontal pull or push to properly shift the .type-bar without strain on its bearings to the printing point. The usual form of keylever however, moves in a vertical direction so that it is necessary to interpose some form of intermediate sub-lever or bell-crank to t-ransmit the movement of the key-lever to the type-bar. By arranging the type-bars in front of the platen so as to swing from an inclined idle position on one side of the vertical plane to an oppositely inclined striking position on the other side of the vertical plane, .the pull is properly exerted thereon by inclined links extending substantially in line with the idle positions of the type-bars and substantially at right angles to the striking positions thereof. The keylevers are caused to move in inclined direction or in line with the connecting links 36 by elevating the rear fulcrum ends, as described, so that the links 36 may be connected directly to the upwardly inclined .rear porltions of the-tfkey-levers without interfering with -the proper transmission ot motion from the' key-levers to the type-bars` That the motion 1s properly transmitted through.

' the direct connecting links 36 is shown by ythe fact that these links are tangent to the arcs on Which their points of connection with the key-levers move or,in other words the links are substantially at right angles to a plane extending through the fulcrums of i @the key-levers and the points of connection between the vkey-levers and links. The pivoted ends of the type-bars are elbowshape and the pull-links 36 are connected to the corners of the elbow-shaped portions so that the links are normally tangent to the i arcs fon which their points of connection with the type-bars move. The rear portions of the bent key-levers, as stated, are preferably substantially parallel to the type-bar segment, e.,`are inclined upwardly and rearwardly at an angle of substantially 45 to the horizontal. The type-bars when in .idle position and the connecting. links are oppositely inclined and are substantially at ri'ght angles to the type-bar segment and rear portions of the key-levers. This arrangement, as stated, permits of direct onepiece connections between the key-levers and type-bars so that the key action of the machine is extremely light and easily operated. Moreover, there is necessarily less lost motion in the key action than where intermediate sub-levers or .bell-cranks are employed and the mechanism is less expensive.

and more durable. It should also be noted that the pull upon the connecting links is in the direct line with the movement of the key-levers and corresponding type-bars so that there is no side strain upon the bearings and joints. The key-levers are considerably longer than the key-levers ordinarily employed without increasing the size of the machine, and the links are connected tothe key-levers at considerable distances from their fulcrums so that the necessary dip .or extent of depression of the several keys is slight and uniform and the machine.

will have an easy, light touch.

In a typewriting machine in which the type-bars are pivotally mounted upon a ring or segment to strike in a common printing point and in which the type-bars are operated by levers connected directly to the type-bars by links, it is necessary, in order to get the proper, straight pull upon all of the type-bars, that the fulcrum of the lever so directly connected, to a type-bar and the point of connection of the lever with its link shall be in a line that is substantially parallel to the type-bar ring or segment and that the connecting llink shall lie and shall move in a direction .substantially at right vangles to such a `line and substantially at right angles to the plane of the segment. In an understrike typewriter, the parts are so disposed that theseconditions maybe fulfilled and at the same time directly connect the type-bars with the key-levers. In a front strike typewriter, however, to get this proper action, it has been found necessary to employ upwardly-projecting sub-levers to which the links may be connected, so that a straight pull or push can be transmitted through the links to the type-bars. With the arrangement set forth, however, the

necessity of employing intermediatel Sublevers is obviated and the type-bars are d-i iectly connected to the key-levers. At the same time the conditions are such that there is a straight effective pull upon all of the type-bars, both at the center and at the ends arranged and move in a direction that is substantially at right angles to this plane and to the plane of the type-bar segment. Moreover, as stated, the pull links are arranged and move in a direction that is substantially in line with the normal positions of the several type-bars and at ri J'ht angles tothe striking position. thereof. is necessary that these conditions be preserved in order that the machine shall have a light and easy key action which shall be substantially uniform at all portions of the keyboard. It should be noted that with` the construction set forth in which the keylevers are elevated at their rear ends and tulcrumed at the upper, rear portion of the machine, that the pull upon the links and type-bars is backward, as well as downward,

. as is necessary in order to properly operate the type-bars both at the 'center and at the ends of the type-bar segment.

The arrangement of all of the type bars.I key levers and connecting links comprised in the full type bar system will be clearly understood from a consideration of Figs. 1, 9, 10 and 11. As appears from Fig. 9 the links Sti at their points of connection with their type bars will lie in arcs indicated 'as 7). e. fl and e corresponding with the four tiers ot hangers, each arc containing the links that. operate on the type bars included in one tier only. lt will be understood that while .in horizontal plan view .these arcs appearf,separated as shown, they will coincide with -one another when viewed from a plane perpendicular to the type bar segment and also to the rear inclined portions of the key levers. ln said Fig. 9 the points of connection of the links with the key levers will lie Iin a curve indicated by the dotted line f. The connections of the left-hand half of the set of links with their respective key levers are more fully shown in Fig. l0 whereiii the links of the three typebars fragmentarily shown in Fig. 11 are designated as, 36a, 3G and 36C. These selected three type bars all lie in the uppermost tier. The type bar Q7 operated by the link 86 is at the middle of the tier.

bar of the tier and thetype bar operated vby the link 3Gb`is between the middle and The type bar oper-- vated by the link 36C is the lett-hand end type illustrative. ot conditions at different points, but also every other type bar of the set or system, receives a straight, direct pull from its associate link, there being no Haring or fair nine' ot the links due to a difference in the width of the type bar system and key lever system. These two systems in the present construction are substantially equalin width i and the links near or at the en'ds of the sysf tem pull as straight as dothe middle links. The actuating links. are all practically par allel and all exert a practically straight pull as nearly as these results can be arrived at b v manufacturing processes. there in the claims there are recitals to the effect thatl the links are arranged and move iira direction at right angles tothe plane of the type bar segment, and to the plane of the rear portions of the key levers. and in line with the type bars, and like recitals bringing .out the construction which enables a practically straight pull of all of the linkson their type bars to be obtained, it is to be under-A stood that this construction is to be followed as nearly as it can be inpractical manufacture, and that it means a straight pull on all ot' the type bars by parallel links as contrasted with a set of links in which there is an intentional, systematic and necessary divergence from parallelism and from a straight pull and also` in which there is a progressive variation of the links in this respect. as they -approach the sides of the system.

By elevating the rear portions of the keylevers the universal. bar and dog-rocker may vbe formed in one piece or mounted to swing upon the same bearings. As indicated in the drawings. the universal bar 37 extends transversely beneath the rear ends of the key-levers and is fixed at its ends to rock a rins 38 extending from a cross shaft 39 -jOurv naled between the rear posts l2 of the machine. A dog-.holder 40 is fixed to or formed in one piece with the universal bar and is provided with a\ pair of escapement dogs 41 of any' usual or suitable construction which coperate with a suitable lescapeinent Wheel 42. The escapement wheel 4Q is Fixed to the lower end of an inclined shaft 43 which is journaled at its vupper end in a bracket 44 projecting rearwardly from the lowercarriage guide rail'lfl. At its .lower end, sha'tt 43 is journaled in the bracket Llthat is fixed to and projects iiiwai'dly from the rear portion of the base of the ii'iachinc. At its upper end lthe esca pement shaft 43 is provided with a pinion ll-(which meshes with a rack 47 that is secured te the carriage. The shaft 39 is pio- Yvided with a pr0]ectmg larm A@which shifts between a pair of stop screws 4S) that are adjustably threaded through lugs'() on the y corner post 12. A' spring 5l extendingbea I tween the arm 48' and a pin 52 on the ina-I chine tame holds the arm 4S normally in engagement with the lower stop screw 49 and holds one ot the dogs normally in engagement with the escapement wheel 4t2. 'llhe improved arrangement thus permits the mounting of one ot the members of the es# capement directly upon the universal bar. lt will be understood that any suitable form of escapement may be employed.

The type-bar segment 9.1 is preferably flat, as stated, and is provided with a broad upper surface upon which the type-barhangers 28 may be firmly secured. The type-bar hangers are formed of sheet metal bent. to a U-shape, as shown, and are preterably arranged side by side in a regular series upon the outer, upper face of the type-bar segment. The segment is provided-with two series of transverse -threaded openings 53 and each ot' the U-shaped hangers is rigidly secured in place by a pair of headed screws 54 extending between the sides of the hangers and engaging the threaded openings 53 of the type-har segment. The hangers are preferably all of uniform height .and each is provided aty its inner portion with a pair of divergent pivot-supporting arms 55 which are ot considerable less 4height than the hangers themselves and are arranged atl different distances from the lower edges ot the hangers so that. when the hangers are mounted in position.y the armsl 54 are arranged in different planes parallel to the segment. The hangers and type-bars are arranged in sets of three or more and, in the form shown, there are tour hangers and type-bars in each set so that the pivot-supporting arms otl each hanger maybe widely separated and are staggered or overlapped with reference to .the corresponding arms on the adjacent hangers'to provide wide pivot bearings tor the tvpc.l' ars. The arms 55 otl the-typebar hangers are provided with openings 5G (see Figs. 6. 7- and 8) at their outer divergent ends to receive the typeTbar pivots 57. Adjacent the inner. ends of the arms 55 are provided with openings 5S, one of which is threaded to receive an adjusting stud or bolt 59. This adjusting stud extends loosely through. one of the openings 58 and is -th-rea'ded into thel other so that the arms of the hangers may be brought together totake up the wear upon the bearings. Each of the adjusting studs is provided with a locknut GO.

The hangers, as stated, are arranged in sets ot' four and the arms 55 of the several hangers in each set are arranged in regular order one above the other and are staggered or overlapped, clearly shown in Figs. 2 and 3. Only two kinds of hangers however are necessary. The first hanger :of the set is shown in Fig. 6 and a similar hanger,

when inverted, will form the fourth or last -like, and may be easily adjusted.

hanger of the set. The projections G1 however, on the hanger are preferably cnt oti' .on the dotted line indicated in Fig. (3 on the last or fourth hanger of the set, so as to permitready access to the adjusting stud and lock-nut on the rst hanger of the next adjacent set. The second and third hangers of each set are illustrated in elevation in Fig. T. The second hanger is set in position there shown while the third hanger is set. in inverted position and the projections 62' thereon are cut off on the dotted line indicated. The hangers are of simple form and are strong and durable. They -are mounted upon the outer face of the type-bar segment where they are readily accessible and may be easily removed for repairs or the By providing two screws for holding each of the hangers, the type-bars are securely held in permanent alinement. Moreover, the alinevment of the type-.bars may be easily and quickly effectedk by entirely loosening` one of the screws and partially loosening the other.

ln machines provided with overlappingl or staggered hangers it is usual to employ type-bars ot diii'erent forms which rende-rs the machine expensive and interferes with the uniformity of the type-bar action. It will be noted that two ot the typc,-barhear ings 56 ot each set of four are arranged below the plane tangent to the platen through the printing` point thereof and the other two bearings arranged above the plane, and that all of the bearings are practically the same radial distance troni the printing point so that the type-bars may all be ot the same lengths. Moreover. by arranging the hangers in sets ot three or more with their pivot-sustaining arms stag' gered or overlapped, long type-bar pivots -may be employed which are uniform in length throughout all portions ot the type ybar segment and the type-bars themselves may be entirely uniform in construction so that the construction is inexpensive and aitfords a key action which is uniform throughout.

' The typeibars are preferably short, heavy and strong and are formed of drop forgings. Their pivoted ends are elbow shaped as stated, the pivots 57 being carried at the. end of the elbow and the openings 63 ,tor the pull links 36 at the corners thereof. Just above the pivoted ends the type-bars are substantially Z-shaped in section, as shown in Fig. 5, so that recesses G4 and G5 and strengthening ribs 66 and (i7 are formed on opposite sides of the type-bars. The cutaway portion or recess 64 on one side ot the type-bar is opposite the4 strengthening rib 67 on the other side and the cutaway portion or recess 65 on the inner side of the type-bar is opposite the strengthening rib 66 on the llt) outer side thereof so that the inner' ends ot' the type-bars are sutiiciently strong' and heavy in spite of the recesses (34 and (35. These recesses permit the close compact arrangement of the type-bars with the pivots third and fourth type-bars ol each -set will -receive the adjacent arms 55 of the First,

second and third hangers when the typebars are in idle position and the recesses 65 on the inner faces of the first, second and third type-bars ot' the set will receive the arms 55 of the second, third and iourth hangers when L .e type-bars are in striking position.

It should be noted that all ot the typebars ai'e entirely similar and uniform in construction so that they are inexpensive to manufacture. Thisis permitted in spite of the fact that the pivot bearing portions are overlapped to provide long` bearings by arranging the hangers and type-bars in setsl of three or more. Moreover, by arrangiine` the pivot bearing arms of the hangers of each set in different planes but all at substantially the saine radial distance from the printing point, type-bars of uniform length may be employed but, when in idle position the ends of the type-bars and the type thereon are not arranged side by side but are staggered and widely separated so that all danger of collision between the type is avoided.

The present invention provides a bar action for visible typewriting machines which is strong, simple and durable in construction in which the number of parts is materially reduced and in which the printing point is in direct line ot' vision of the operator.

lt is obvious that numerous changes may be made in the details set forth without departure from the essentials ofthe invention as set forth in the claims.

Having described my invention, what l claim as new and desire to secure by Letters latent, is
